Why not scrap income tax altogether and tax land value? It seems insane to me to punish people getting better jobs. But by owning expensive land you are in effect depriving others of using it. If you want to argue a moral basis for taxation, that is surely one. Taxing career advancement instead of property investment and absentee land owners sitting on property seems completely backward. But I never considered that tax laws were probably designed from day 1 to benefit the rich, since the wealthy are so much more influential in any government (including democracies).
